AI Technical Summary

Benefits of technology

The present invention is a test, drain, and adjustable pressure relief module for a sprinkler system. It has three independent flow ports: an inlet, an adjustable pressure relief valve, and an outlet. The module allows for selective adjustment of the pressure required to open the valve and discharge fluid. It also has an internal flow valve that can direct flow between the inlet and the second or third port. The technical effect of this invention is to provide a convenient and flexible tool for testing, draining, and adjusting the pressure of a sprinkler system.

Problems solved by technology

One drawback of conventional sprinkler systems is that the pressure relief valve of the sprinkler system, designed to vent when the pressure within the system exceeds normal operating pressure, opens before reaching the testing pressure, thereby preventing the system from reaching the testing pressure.
Such a process is clearly inefficient, wasting both time and resources.

Abstract

A test, drain and adjustable pressure relief module for a sprinkler system has a single body with three independent and fluidly connectable flow ports. A first port of the three flow ports is fluidly connectable at an inlet side thereof to the sprinkler system. A second port of the three flow ports has an adjustable pressure relief valve removably mounted to an outlet thereof. The valve is biased into a closed position and a threshold pressure is required to open the valve and discharge fluid is selectively adjustable. A third port of the three flow ports has an open outlet end configured to removably connect with a drainage pipe. The three ports form a Tee connection and have a flow valve therebetween to selectively direct flow between an outlet of the first port and at least one of the respective inlets of the second and third ports.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority from U.S. Provisional Patent Application No. 62 / 443,326, titled “Control Valve Assembly with Test, Drain and Adjustable Pressure Relief Valve”, filed on Jan. 6, 2017, the entire contents of which are incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]The present invention is generally directed to a fluid flow control valve assembly, and more particularly to a sprinkler system control valve assembly having a test, drain and adjustable pressure relief valve.[0003]In order to comply with certification and licensure requirements, automatic fire sprinkler systems are required to be periodically inspected and tested in accordance with the standards set by the National Fire Protection Association (“NFPA”). Under such standards, a pressure test is periodically performed on a sprinkler system to ensure that the system does not leak.[0004]Generally, the pressure test requires pressurizing the system d...
